"Unkown Disc" On one DVD+r diskI recorded seperately 2 videos in LP mode. OK I then recorded a third video in SLP mode. When I attempted to look at the program material on this disk, I got the message, "Unkownd Disk" Is this problem solvable? Joe Maltz

I suppose a Special-mode long-play video playback may not have problem.

LP can be used in times when quality is not important, but you need to get more time out of your tape (eg. shooting for the internet, testing effects and gear, long events)

SP should be used when quality is more important, even though you lose a bit of time from the tape (eg. movies, home videos, music videos, sports)

SLP (super long play)I suppose a Special-mode long-play video playback may not have problem.

Turn on the TV and set it to the video source to be able to easily see the menus as you set up the dubbing process. Put the source tape you want to record in the VCR. (Copy protected tapes will not be dubbed.) If you want to avoid dubbing from the DVD to the VHS tape, remove the erase protection tab from the cassette. Put a compatible recordable disc (non-finalized disc, unprotected disc) in the recorder and make sure there is sufficient available capacity on the disc.

Press Rec Mode/Speed to set the speed (SP, LP, SLP, or XP). Press DVD/VCR and set the unit to VCR mode. Confirm the mode with the indicator light on the unit. Press Dubbing and the mode should switch to DVD automatically. Select Yes (with the left/right arrows) and press Enter to start the duplication. The unit should indicate the VCR playback, dub and DVD recording are in progress. Press Stop to halt the dubbing process or it will stop when the unit reached the end of the tape or the disc is full.

The dubbing button is only on the remote control; if your original remote isn't working make sure that your replacement remote has the feature. Remotes.com often has exact or substitute remotes with the matching features. Search just by the model number not the brand.

The manual isn't too helpful either - "Recording error other than below," it says. There are a couple of possibilities. The Philips/Magnavox/Funai recorders automatically record in VR mode when you use +R discs (there are two possible recording modes - V Mode and VR Mode). Is it possible that you have switched disc types lately? If you are currently using -R discs, switch to +R and vice versa. The manual states that +/-RW discs take a while to initialize.

I couldn't find a full factory reset on that one, so you may have to unplug the unit for about 20 minutes to restore all the defaults.

Another possibility: Finalization requires some extra space on the disc. If you accidentally pressed the button that changes the recording format between SP, EP, LP, etc., you may not be able to fit the same amount of video on the disc that you were able to fit before. You can change the format by pressing the Disc Mode button on the remote - LP Mode will fit 3 hours worth of recordings onto a 2-hr disc and is considered a "medium quality" recording. Try changing the Disc Mode to LP and see if it will finalize the next disc that you record. The downside of this possibility is that the discs that you have already made that are giving you errors are not "fixable" - you will will have to re-record the shows to a new disc in LP mode.

First, you will need to know if the program was recorded in XP mode, SP mode, LP mode, or EP mode. To find out how much room there is left, put the dvd in the tray and press the Disc Menu/List button on the JVC remote. This will display the title and how long it is - write that number down. It will also say either "XP,SP, LP, or EP" - write down that mode. In XP mode, a DVD will hold 1 hr and 20 mins worth of prgramming - MAXIMUM. SP mode = 2 hours. LP mode = 4 hours. EP = 6 hours. So, if your program is one hour, and you recorded in LP mode, you have 4 - 1 = 3 hours of space left for recording on that disc.

If you finalize a disc, you will no longer be able to add more programs to that disc, unless the disc is a + or - RW disc. Also note that finalization requires some disc space, so if you recorded a program that is exactly 1hr and 20 mins long, and you recorded it in XP mode, then the disc will probably not finalize correctly.

Dont use xp mode. Here are the definitions:
SP is short for Standard Play. Standard play allows you to record information onto the tape the way it was intended, with no quality loss. By default, VCRs and camcorders will record your footage as standard play. On a standard VHS tape, recording footage in SP mode will yield 2 hours of video.
LP is short for Long Play. Long play allows you to record much more information at the expense of quality. It accomplishes this by reducing the speed the tape is run through the VCR. As the tape speed decreases, the quality will also decrease. You’ll notice this effect when comparing a tape recorded at LP versus one recorded at SP, especially after years of storage. The LP tape will appear more blurred, have more tracking and color issues than tapes recorded at SP. A VHS tape recorded at LP can hold roughly 4 hours of video.
EP/SLP is short for extended play. Extended play is similar to LP, but actually provides you even more recording time. EP was primarily used to document long, continuous events without the need to change video tapes every 2 hours. Due to the fact that the video is not of optimal quality, many times this setting was not used in order to preserve the quality of your footage. Tapes recorded at EP usually are the most problematic after years of storage, displaying a wide variety of tape damage symptoms including color loss, audio loss, frame skipping, and tracking issues.
